Electron Beam Welding is a type of fusion welding process in which a high beam of electrons hit the metals, melts and then solidifies to form a joint. It is used for high precision welds mainly in Aerospace industries. Fusion zone is very narrow with deep penetration and heat affected zones are very less when compared with other welding techniques. The metals melts and form an intermetallic compound which binds the base metals. The formed intermetallic compound acts as an alloy with high strength and possess the properties of both base metals. The analysis of intermetallic compound is very imp
There is a gap in defining the multi-criteria decision-making issues and with recommendation techniques and theories that can help develop the modulation coefficient recommenders. The main objective of this research is to identify an in-depth examination of the category of multiple variables recommendation systems. The current research focused on the group of multiple-criteria ranking recommenders' methods, which make recommendations by representing an individual's performance for the product as an ordered collection of rankings in addition to different parameters. The techniques used to make
Due to the adverse environmental effects associated with large hydroelectric dams and traditional diesel power plants, there is a pressing need to investigate alternative renewable energy options. Gravitational Vortex Turbines emerge as a promising solution, offering clean energy for off-grid regions, by harnessing the power of water vortexes in turbine-generator systems. The global adoption of these turbines has risen in response to demographic expansion in remote areas, and ongoing research has contributed to refining their efficiency. Despite the increasing deployment of GVTs, a notable gap
In the present study, we extend the utilization of contractions to b-metric spaces by utilizing simulation functions. We will conduct research into the Istratescu type contractions, a type of contractions that have simulation functions produced in them, and we will demonstrate new fixed-point solutions for this type. By doing this, we want to provide further light on the characteristics of b-metric spaces and contribute to the continued improvement of fixed-point theory in this field. The results of this study are significant because they are supported by examples that are presented, giving co
This article discusses the comparison of simulated and experimental data for a solar heat supply system based on flat collectors integrated into an office building to meet the need for heat. A new design of a flat solar collector has been developed, in which thermal insulation occurs in a heat-insulating transparent double-glazed window. Also, to reduce the radiation on the surface of the heat receiver, a selective coating was used to prevent heating from infrared radiation. The TRNSYS model has been developed and tested on experimental data and then used for optimization purposes. Temperatu
